Long story, please bear with me.
Whilst driving, error messages would appear in succession:
Run Flat indicator Inoperative;
PRE-SAFE Inoperative;
Restraint System Malfunction;
Cruise Control and SPEEDTRONIC Inoperative;
ABS and ESP Inoperative.
The radio dies and the speedometer and direction indicators stop working. Continued driving, the car is in limp mode with the engine revving at about 4000 rpm for less than 60 Km/hour. The radiator cooling fan runs flat-out. Stopping and restarting does not help.
Initially, I thought going over a bump cured the problem pointing to a possible loose earth as suggested by some. Lately, no bump needed, everything would just start working normally again. Also leaving the car standing, switched off for about 25 minutes, it also self-heals, pointing to a possible faulty electronic component cooling down. This problem used to be a once in a while occurrence but now happens more frequently and I am worried that shortly, it will leave me stranded. I have improved the taillights’ earths and checked every earth I could find.
I have managed to get to an Indy whilst in this error state but the diagnostics would not give any reading, pointing to a power issue per the technician. He then pulled the engine control module and the car (obviously) died. He replaced the module; the car started and was cured. He then was able to run diagnostics (below). I have since tried the same trick, pulling the module, but it did not work for me and I stood for 25 minutes for it to self-heal again.
Unfortunately, the Indy’s computer did not have a printout facility but I took photos of three screens:
20D3-000 Check component Y27/9 (Left EGR positioner). Short circuit to ground
0E7-002 Check component Y94 (Quality control valve). Open circuit in wiring.

Someone else had a similar problem and found a dry joint in a (joining?) component in the cabling next to the driver’s seat. I could not see any problem in mine but my eyesight is not what it used to be and I could not inspect the one closer to the firewall.
It was suggested that it could be a CAN issue (the “fuse box” into which the engine control module and other fuses and modules plug?), but unfortunately, the Indy has no replacement units available for a swap-out. Buying one for this purpose is an option but with no guarantee it will solve the problem, I am loathe doing this.
As it stands it is a very nice car with only 103,000kms, well designed and a pleasure to drive – when it goes. Presently, it is unreliable and a risk to use. My wife (rightly), now refuses to drive it and I cannot sell it with a clear conscience in this condition.
Short of giving the agents (or an Indy) a blank cheque, any suggestions what the problem could be or anything I could try?
